PWR-DSP3 Amplifier specifications
The PWR-DSP3 is an amplifier with total of 2400W limit by its power supply. The following electrical specifications show
the typical operating
Thermal specifications
NOTE
: Channel 2 and 3 of the amplifier are single Ended amplifier designs which can pump back energy on the
power supply. At low frequencies this can cause asymmetrical power supply voltage rails, resulting in premature
clipping of the amplifier outputs or over-voltage protection of the power supply. When channel 2 and 3 are used to
amplify low frequency signals E.G with monitors, please take following actions.
Input for channel 2 should be inverted inside the DSP. This will cancel the supply pumping between channel 2 and 3.
In order to have outputs of channel 2 and channel 3 in phase, the output of channel 2 should be phase inverted by
interchanging the + and – connections for the speaker. Please see drawing below.
